Senior Firmware Engineer

Renesas Electronics America is seeking a Senior Firmware Verification Engineer to join the Infrastructure Power team. This role owns pre-silicon verification of embedded firmware used to control high-performance power management ICs for data center AI accelerator networking and computing platforms. The engineer will apply a solid understanding of the firmware development process to build effective test strategies verify ARM Cortex-M firmware in simulation-based environments and identify firmware RTL and interface defects before silicon availability. 

Key Responsibilities 

  Build maintain and enhance SystemVerilog-based simulation tests and environments that execute ARM Cortex-M firmware with the associated RTL and hardware models. 

  Verify firmware behavior across reset boot initialization configuration sequencing telemetry protection fault handling recovery and firmwarehardware interface scenarios. 

  Analyze C and assembly firmware at source instruction register memory interrupt and peripheral levels to diagnose functional and timing-related failures. 

  Develop directed constrained-random negative stress boundary and error-injection tests to validate expected behavior and robustness. 

  Run regressions; triage failures; perform waveform log memory and register analysis; and isolate issues to firmware RTL models testbench or tools. 

  Define and track requirements coverage functional coverage code coverage and regression quality; identify gaps and drive closure. 

  Create automation using Python Perl or similar scripting languages for build and test execution result checking log parsing failure classification reporting and continuous integration. 

  Collaborate closely with firmware developers RTL designers architects and validation engineers to review requirements improve observability and controllability reproduce defects and verify fixes. 

  Document verification plans test procedures coverage results debug findings known issues and release-readiness assessments. 

Qualifications :

Required Qualifications 

  BS or MS in Electrical Engineering Computer Engineering Computer Science or a related technical field. 

  Deep understanding of C and assembly-based firmware for ARM Cortex-M processors including exception and interrupt handling memory maps startup code registers peripherals and low-level debugging. 

  Strong ability to debug firmwarehardware interactions using simulation logs waveforms memory and register traces and source-level analysis. 

  Experience in firmware verification embedded firmware testing firmware development or pre-silicon verification. 

  Proficiency in Python Perl or similar languages for verification automation and regression infrastructure. 

  Strong understanding of the embedded firmware development process and how requirements architecture implementation integration test debug and release activities connect. 

  Proven firmware testing experience including test planning test-case design negative and boundary testing regression analysis defect isolation and coverage closure. 

  Familiarity with embedded interfaces such as I2C PMBus SPI UART or similar protocols. 

  Strong analytical problem-solving written communication and cross-functional collaboration skills. 

Preferred Qualifications 

  Experience verifying PMIC firmware digital power management voltage regulation sequencing telemetry or protection features. 

  Hands-on experience developing maintaining or debugging SystemVerilog-based pre-silicon simulation environments. 

  Experience with waveform and debug tools such as SimVision Verdi or similar tools. 

  Working knowledge of RTL design and firmware-controlled digital subsystems. 

  Experience with CI/CD pipelines automated regression farms test dashboards and scalable failure-triage workflows. 

  Experience improving firmware testability through assertions monitors scoreboards reference models hooks or diagnostic instrumentation. 

  Post-silicon bring-up or lab-debug experience is beneficial but is not the primary focus of this role. 

  Experience with QEMU emulation FPGA-based prototyping virtual platforms or other pre-silicon execution environments. 

  Exposure to UVM or other structured verification methodologies and coverage-driven verification.
